How the protective collar works

Interview: Sebastian Kuszmierczyk

Unpleasant for ticks and fleas

How does the collar help to prevent the transmission of disease pathogens?

The active ingredients make the dog’s skin extremely unpleasant for ticks - when they touch the dog’s skin, it feels like touching a hot stove plate, so they drop off. This is called the “hot foot effect”. Both fleas and ticks die if they come into contact with the active ingredients. As they don’t need to bite, the risk of disease transmission is lower.

In how many countries is Seresto marketed?

Seresto is available in 57 countries in Europe, the United States, Asia and Africa.
